What We Do

The Sandoval County Assessor’s office is committed to serving the citizens of Sandoval County by providing fair and uniform assessments through equitable administration and competent interpretation of the New Mexico State Property Tax Code.

How We Serve You

The Sandoval County Assessor’s Office determines the property value of homes, businesses and other taxable properties within the county for ad valorem tax purposes. The office also prepares the tax rolls for the County Treasurer for real property (land and improvements), personal property (business equipment), livestock and mobile homes. The Assessor’s Office also lists and maintains the records of all real and business personal property located in Sandoval County. The office mails notices of property valuation, assists taxpayers in claiming exemption and maintains correct property ownership based on documents filed with the County Clerk’s office.

The property tax code requires the Assessor’s Office to mail notices of property valuation by April 1st of each year. It’s important for property owners to review the valuation figures on the Notice of Value, because this is the last step in the review process. The value on the notice is what will be used to calculate the taxes you will pay after your local government agencies and school districts set their budgets and the tax rates are adopted.

County appraisers review the real estate data and add new property to continue updating the values of existing land and buildings. Taxable value on real and property is one third of the total appraised value, minus any allowable exemptions, such as head-of-household or veteran’s exemptions. The net taxable value is then multiplied by the tax rate to determine the actual taxes property owners are billed. Property in New Mexico is classified as residential or non-residential and is taxed at different rates.
